Abstract

The invention discloses a system interaction method and device of a trusted computing platform based on a dual-system architecture. The method comprises the following steps: powering a computer, dividing hardware resources of a computer into protection hardware resources and calculation hardware resources; wherein the computing hardware resources are allowed to be accessed by the protected hardware resources and cannot be accessed by the protected hardware resources, using the protected hardware resources for operating the protection subsystem, using the computing hardware resources for operating the computing subsystem, and using the protection subsystem for cooperating with the trusted platform control module to complete measurement of the computing subsystem; and interacting between thetrusted platform control module and the computing subsystem according to an interaction mode matched with the interaction type. According to the invention, the technical problem of relatively low computer security in related technologies is solved.

Description

technical field [0001] The present invention relates to the field of Internet security, in particular to a system interaction method and device based on a trusted computing platform with dual architectures. Background technique [0002] The current cyberspace is extremely fragile. Stuxnet, ransomware (such as Wannacry), Mirai virus and other cyber attacks that have caused great impact emerge in endlessly and become increasingly rampant. The problem is that blindly adopting the "blocking and killing" passive defense methods represented by "firewall", "virus scanning and killing", "intrusion detection" and so on is hard to defend against, especially in the face of attacks aimed at the vulnerabilities of the target system. Unable to defend effectively. [0003] The trusted computing chip TPM proposed by the international TCG organization (English full name Trusted Computing Group, Chinese name Trusted Computing Organization) is used as an external device of a computer. Static...
